pressures in excess of 1/2 psig. (3.5 kPa). The appliance must be isolated from the gas supply piping system by closing its indi- vidual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig. (3.5 kPa).

CAUTION: Do not kink flex- ible gas line.

CAUTION: Compounds used on threaded joints of gas piping shall be resistant to the action of Liquefied Petroleum (LP or pro- pane), and should be applied lightly to ensure excess sealant does not enter the gas line.

1.Install a sediment trap between the in- coming gas line and the gas control valve (see Figure 39). The sediment trap should extend down the center of the pipe. Refer to your local codes.

2.Prepare incoming gas line and check with local codes regarding the use of teflon tape. Complete your gas line in-

stallation by connecting incoming gas line with flexible gas line. Secure tightly with a wrench, but Do NOT

Overtighten.

WARNING: All gas piping and connections must be tested for leaks after the installation is completed.

After ensuring that the gas valve is open, apply a soap and water solution to all connections and joints. If bubbles appear, leaks can be detected and corrected.

Do not use an open flame for leak testing and do not operate any appliance if a leak is detected.

WARNING: Improper installa- tion, adjustment, alteration, ser- vice, or maintenance can cause injury or property damage. Refer to this manual. For assistance or additional information, consult a qualified installer, service agency, or gas supplier.

GAS LINE HOOK-UP

should be done by your gas sup- plier or a qualified service person.

A manual shut-off valve has been included in the appliance’s gas supply system. You may consider installing an extra gas shut-off valve outside the appliance’s enclosure (check with local codes) where it can be accessed more conveniently with a key through a wall as shown in Figure 38.

Route a 1/2” NPT black iron gas line to- wards the appliance coming in from the left. It is recommended to route the pipe between the stand of the firebox and the surround of the fireplace (see Figure 39).

IMPORTANT: The appliance and its indi- vidual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test
